Edit: the 2nd edition has now been published (October 9, 2012), with 25 fewer "warmup" puzzles,and 25 more difficult puzzles. The printed book now also has an ISBN, so hopefully after about2 months the book will be on Amazon...

After months of delays and confusion with lulu.com, I decided to publishthe 2nd edition of the Killer Sudoku book (which is identical to the 1st, buthas the solutions in the back) using "createspace" (Amazon's self-publishing arm).

I must say things went _much_ more smoothly, and they charge less than "lulu",which will leave me about $2 a sale (instead of $0.01..)
